To allwkom it may 007L067? I Be it known that, I, ALBERT A. WEBER, a citizen of the United States, residing atSacra'mento, in the county of Sacramento and State of California, have invented certain new and useful Improvements in Oil and Dust Pro'of Journal-Boxes, of which the following is a specification.

- This invention relates to improvementsin' journal boxes andthe principal object is to provide an oil and dust proof box which will thoroughly protect the journal, hearing from injury Another object of the invention resides in the provision of a novel'cover plate and cap for the journal box.

' With the above and other objects in view as will become more apparent as the description proceeds, 'the'invention consists in the novel combination and arrangement of parts as will be fully set forth in the following specification, claimed andillustrated in the accompanying drawing, in which,

' Figure '1, is a perspective view oi a journal box constructed in accordance with this in' .vention,

Fig. 2,- is a longitudinal sectional view through Fig. 1, V

Fig. 3. is a transverse sectional view through Fig- 1, p

Fig. i is a perspective View of the cap,

. Fig. 5, is a detail perspective view of the Referring to the drawings by characters of reference, the numeral 1, designates as an entirety the journal box, which comprises a bottom wall 2 having formed along its sideedges the side walls 3, which are connected at their upper edge by a top'wall 4. The. side walls are continued forwardly inter-. mediatetheir upper and lower edges to' form inclinededges, the lowermost of which are connected by a front wall 5. A rear wall 6, is provided and connects the bottom, top and side walls and thisrear. wall is formed with an elongated vertically extending aperture 7, through which the end of the axle 8 extends. Flanges 9 are formed on the edges and bottom flanges, designated by the numeral 9, are slightly ofi'set to form guides for the cover elements which will be more fully hereinafter described. A. journal hearone of which where the axle enters the same, dust tight than the plates. The flanges extend beyond 14, is provided which consists oi a plat-e 15, formed with an angularly extending flange 16, arranged. along its upper edge.

This plate 15, has formed near its lower edge at an inclined rib 17, the lower wall or which is adapted to engage the inner face of the upper edge of the frontwall 5, when the dc vice is assembled. Vertically extending arms 18, are formed at the ends cf the rib 17, and are adapted to engage the inner faces-- of the forward edges of the side walls 3 while the flange 16, lies on the up er sic. of the forward edge of the top wall and i provided with a screw receiving cpcrlin.;, which registers with a similar threadeopening formed in the top wall. A screw 19, is adapted to lit in the said openings and. forms the retainingsneans for the'can. The rear end of the box is closed cover plate formed in two separate secti view of the fact that the other section identical in constrncticn, but one will shown and described. Each sections? the said cover plate consists of a back wall 29, provided at its top andbottoin edge with flange 21, terminating in a right-angiilarl extending flange 22, which in conjunction with the flange 21, forms a trough shaped. structure, into which the oii'set flanges of the box fit when the device is assembled. One edge of the back wall is formed with a side flange 23, which connects the end 21, so that the whole forms a snbstanti. box shaped s ructure. The edge of the wall 20, opposite that on which the flange 23, is formed is provided with a recess, which is preferably slightly elongated to allow the axle a slight vertical movement the journal box. I o In order to completely close the box and render the same dust tight around the pointgasket is provided, which is best illustrated in Fig. 5, and consists of two plates 2% and 25, each of which is provided with flanges 26, which as shown are of less thickness the adjacent ends "of the plates and torn;

guides, so that the plates may he slid relatively to each other longitudinal alineend any danger of th same becoming displaced will be avoided. n he end of each plate is formed "vith an arcnate recess and when the plates are assembled and in place it will be readily recognized that a substantially circularrecess for the reception of the axle is provided, which is so arranged that the Walls thereof may give vertically and yet remain at all times in contact With" the said axle. Gne of the plates, namel that designated by the numeral 24, is -ormed j with a longitudinal recess 27, While the other is provided with the leaf springs 28. A suitable coiled spring 29, is seated in the recess 27, and tends to normally force the plate 24, upwardly against the axle in order to assure a tight fit between the parts.

in use it will be seen that the device is assembled in the manner shown in Figs. 2 and 8, so that theplates 24: and 25 forming gasket, are positioned between the back and the cover plate. When it is dev- 'l wall 0,

" sired to gain entrance to the front end of the box, the screw 19, is removed and the cap may then be easily removed. in order that the end of the box may be opened, it is necessary to slide the cover plate sections oil laterally, at which time the gasket 'Will be exposed and may be readily removed from Within the box, thus leaving the same entirely open. Due to the resiliency of the of the gasket againstthe axle it will be readily understood that no special care is necessary in ire-assembling the device except to see that the parts are properly related end itlis evident that the device is acc ssible.

repairs, (I lie in the foregoing there has been thus facilitating the malcdescribed, and shown a particular type of this invention it is to be understood that certain minor changes in the details of construction, combination and arrangement of parts may be resorted to Without departing from the spirit of the invention as claimed.

What is claimed is 1. In a journal box, a gasket comprising a pair of plates, each having an axle receiving recess formed in one end, the plates fitting together so as to cause the recesses to forman opening through which the axle fits, means to force one of the plates against the axle and means to yieldably hold the plates together.

2. In a journal box, a gasket comprising a pair of plates, flanges on the plates, the flanges being extended beyond the ends of the plates, the ends of the plates beyond which the flanges extend being recessed to receive an axle, the plates beingslidable on.

the flanges with relation to each other,

means to force one of the plates against the axle and means to yieldably hold the flanges together. v

' In a ournal box, a box having an opening formed 1n its rear Wall, flanges formed on the edges of the rear Wall, a cap comprising a pair ,of plates each having a recess formed therein, flanges on the plate forming troughs to receive the flanges on the rear Wall of the box, a gasket comprising a pair of plates, each having a recess in one endadapted to fit around an axle, guide flanges formed on each plate whereby the plates may slide longitudinally, means to yieldably hold one of the plates against the axle and means to hold the plates yieldably against eaofi other and between the cap and rear We ALBERT A, WEBER.
